As shown in FIG. 7 , the inner tubular portion 45 of the valve portion 31A is inserted into the outer tubular portion 53 of the water receiving side joint portion 32 . In a state where the inner tubular portion 45 is inserted into the outer tubular portion 53, the connection between the outer peripheral surface of the inner tubular portion 45 and the inner peripheral surface of the outer tubular portion 53, in other words, the connection between the joint inner passage 52 and the inflow passage 43 The part is made watertight by a sealing ring 46 . In a state in which the inner cylinder portion 45 is inserted into the outer cylinder portion 53, the flange 44 of the valve portion 31A and the flange 55 of the water receiving side joint portion 32 overlap in the front-rear direction.

As shown in FIGS. 10 and 11, when the flange 44 and the flange 55 are superimposed, the position of the screw hole 44a of the flange 44 and the position of the second screw hole 55b of the flange 55 are different in the vertical and horizontal directions. are agreed with respect to In a state in which the flange 44 and the flange 55 are overlapped, the position of the positioning recess 44b of the flange 44 and the position of the positioning protrusion 55c of the flange 55 are aligned in the vertical and horizontal directions, and the positioning recess 44b and the positioning protrusion 55c are aligned. are mated.

With the flanges 44 and 55 superimposed on each other, a screw 56 passed from the screw hole 44a to the second screw hole 55b and a nut 57 non-rotatably held in a pocket 55d of the flange 55 (see FIG. 12). The valve portion 31A and the water receiving side joint portion 32 are fixed to each other.

Therefore, the positioning concave portion 44b and the positioning convex portion 55c cannot be fitted, the flange 44 and the flange 55 cannot overlap, and the connection between the valve portion 31A and the water receiving side joint portion 32 is impossible.

In such a case, if the positioning convex portion 55c is removed from the flange 55, the water receiving side joint portion 32 loses vertical directionality when connecting to the valve portion 31A, and an emergency measure is possible. is. However, when the positioning convex portion 55c is removed from the flange 55, when a stress acts between the valve portion 31A and the water receiving side joint portion 32 in the direction of relative rotation about the axis L, the stress is removed for positioning. Since the fitting portion between the concave portion 44b and the positioning convex portion 55c cannot bear the load, the load on the screw hole 44a, the second screw hole 55b, the screw 56, etc. increases.

In order to solve such a problem, the valve portion 31B configured as shown in FIGS. 20 and 21 may be used. The only difference between the valve portion 31B and the valve portion 31A shown in FIG. 11 is the position of the positioning recess 44b in the flange 44, and the rest of the configuration is the same. That is, the positioning recess 44b of the valve portion 31B is provided on the left edge of the rear surface of the flange 44. As shown in FIG.

Therefore, with the opening of the push-in joint 54 facing upward, in other words, with the opening of the push-in joint 54 facing the ceiling of the room, the position of the positioning recess 44b of the flange 44 and the position of the positioning protrusion 55c of the flange 55 are determined. are matched in the vertical direction and the horizontal direction, so that the water receiving side joint portion 32 and the valve portion 31B can be connected. Therefore, when the water supply pipe 115 extends vertically from the upper side of the opening 12, that is, from the ceiling side of the room to the opening 12, the valve portion 31B can be suitably used.
